Be it. known that l, PAUL Honnmo, a sub .ject of the King of Wurtemberg,and resident Combustihls, of which the following is a full,

clear, and exact description.

My invention relates to improvements in the manufacture of coke fromaqueous, bitumi o us combustibles, such as peat, brown coal, river-mud,and the like.

In my invention I do not permit the escape of steam from the substancesoperated upon. The steam is generated in great quantities during thedryin of aqueous bituminous combustibles, Whic precedes the coking, andI utilize this steam by causing it to act upon the material to he ooked,for which coking a coke-oven of any kind may be used.

The essential feature of my process consists in heating the aqueousbituminous coinbustible to the exclusion of air, and in conducting thesteam generated thereby, which in some cases contains small admixturesof distillation gases,.into the coking-zone of an oven for theproduction of coke.

My process constitutes an impiovement upon similar processes now in use.Besides utilizing the steam generated during the coking of the saidaqueous, bituminous combustihles and thus saving the heat-energyconsumed in the generation of the same for effecting a chemicalreaction, an increased yield of ammonia, tar and gas is attained by thisprocess.

My process can be carried 01m in different Ways: 1. By conducting thesteam generated in the drying of the aqueous, bituminous combustiblestogether with any admire tures oi distillatiomgases it may contain,

generated during the drying, directly to the material which is beingcokcd at a higher temperature and then expelling the Water gas formed bythe decomposed steam from the coke-oven. 2. By first superheating thesaid steam and admixtures oi gz'tses-it ma contain, and thereuponconducting it to the material which is being coked at a higher 0.oeraturc.

The collection of the steam and the conr in of lhc more to the materialfrom which islwiuu extracied may he cll'ccted in L mircnt ways, l preferan oven, which illustrated in :zw anocxrd dra ings and in my pendingapplication filed May 3. Hing-L, Serial No. 258,474. But it is LVlrlolllthat other suitable ovens may be used for ('orl ing out my invention.For conducting l'l'w steam into the coking-zone I recomnn-nd difierentmeans. v

The steam may be either conducted by a suction-conduit leading into thecoking-mm of the oven, through which is eil'cctcd, by means ofsuckingnpparatus, such as c.\'- hausters and the like, the sucking ol'iliu steam and the conduction of the same inhthe coking-zoneof the oven,the passing of the same through this zone and the (I\']')(llllif of theWgrtei gas out of the coking-zone and out of the oven. The steam may,however, also be conducted to the materinlwhich is being degusified in amanner that the colicoven is closed at the top and has only on out:- letin the coking-zone. The steam generated is then driven. by its owntension through the material in the oven, and passing through the--roking-zone forms Water gas which escapes from the oven. My newprocess does not require that-the drying and the coking of the or. ucousointminous qomhustibles should tidie place in one and the some oven. Thedrying may be ellected in a special ovenand'thc steam greneratebl maybcnonductcd to another oven in which the same or another materialcoltcd. On the whole I prefer however to do the drying and the coking;ol" the imitcrhd in one and the same oven. in order to reduce, as. intpossible, the resistance the strain meets with on its way through thenmtvriul, l proh-r to rovide special conduits. channels or cham- )crsconnecting the zone in which the drying of the combustible takesplzmwith the cult: ing-zonc.

in carrying out my new prorcssy. the stesm generated together with itsadmixtures, will in this cas stream from the (loving-zone into the saidconduits and bc romhicted t-l-irough the some into the r-olvine uaone.The conduils only he in the inside or on the outside,

or the oven, moreover, heat may he rou ducted to the conduits fromthroutside for.

the purpose of lorrhcatiiug or ovcrheiding the steam.

My above descrihcd process is not idcnticui with processes alreadyknown, in which likewise gases are genm'utcd, which we conducted fromcolder parts oi the oven into the warmer zones of the same. But withthose processes there is no question of the produc-- tion. of coke, butof the gasificatien of the combustible, and. further of a superhez'ttingof tar-oils for the fixing of gases. With my new process coke is to bereduced and the tar-oils are, as far as possiblis, to be preserved atthe same time.

In the furnace shown in the drawing, wherein Figure l is a verticalsection, and Fig. 2 a transverse section on line 1 of Fig. l, thematerial is fed thereto through the shalt or aperture C when the closingplate (A has been opened. Through the latter passes a movable red I)cormccted with a valve 0. By means of this valve the chambers and c ofthe furnace can be placed in communicatien with each other when desired.

The prclin'iinary drying of the material to be coked takes place in thechamber (Z from which the material passes to the chamber 0 through thevalve (1 which is opened at intervals. In the chamber (1 the extraction.oF gas and coking of the material takes place. The steam produced by thedrying process in the chamber (1 comlueted downwards through cnambcrs orconduits f to the chamber .c where it is decomposed into water-gas whichcirculates in the coking zone and passes out through. the conduit ztogether with the gases produced by the coking process. The removal ofthe gases from the chamber 6 is efl'ectcd by means of an exhaust tan 9or the like. The Whole or part of the gases is admitted to the chamberit through the flue Z, or a part of the gases can be conveyed throughthe pipes rand-9 to other apparatus in which their heat. utilized, orcondensation or other treatment of the gases takes place. hen. a portionof thegases are to be conveyed to another apparatus the valve or theslide 25, arranged in the pipe 8, is opened and the valve or slide it,arranged in the pipe 7", is closed. But the valve 1 being closed and thevalve 14 being opened the gas exhausted from the chamber 6 isconveyed/through the pipe r to a pipe e through which it enters into thechamber h together with the heating gases generated in another plant. inthis chamber 7L inclosed by the bi."icl-:'\vork jacket B, the gasesareburned and efi'eet the ex ternal heating of the retort A. The productsof combustioniinally escape by an exit 11).

, The air necessary for the combustion of the gases may enter through anair inlet a", (preferably arranged near the pipe 7;.) The removal thematerial from the chamber a takes place through the curved conduit 7r,in which the inclined slide t is arranged.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The process herein described oi coking aqueousbituminous rrmibustibles, consisting in heating such combustibles underthe exclusion of atmospheric air, and then admitting the steam generatedfrom the said com bustibles with any small admixture of gases it maycontain, into the coking-zone ol an oven for the production of coke.
